Usage (Hashing)

use ascon_hash::{AsconHash256, Digest};

let mut hasher = AsconHash256::new();
hasher.update(b"some bytes");
let digest = hasher.finalize();
assert_eq!(&digest[..], b"\xe9\x09\xc2\xf6\xda\x9c\xb3\x02\x84\x23\x26\x5c\x8f\x23\xfc\x2d\x26\xbf\xc0\xf3\xdb\x70\x46\x83\xef\x16\xb7\x87\xa9\x45\xed\x68");

Usage (XOF)

use ascon_hash::{AsconXof128, ExtendableOutput, Update, XofReader};

let mut xof = AsconXof128::default();
xof.update(b"some bytes");
let mut reader = xof.finalize_xof();
let mut dst = [0u8; 5];
reader.read(&mut dst);
assert_eq!(&dst, b"\x8c\x7d\xd1\x14\xa0");
